These spectacular images of the Earth are the most true-colour images of the entire world released to date, according to Nasa scientists.
The images of the Indian Ocean and North America were produced by researchers at
Goddard Space Flight Center using images from the Terra satellite more than 700km (435 miles) above the Earth's surface.
Blue Marble series
was pieced together from thousands of images taken over many months by the satellite's remote-sensing device Modis, of every square kilometre of the Earth's surface.
